The focus of our trip is to photograph not only the many diverse species of birdlife in this country, but also other interesting mammals, invertebrates and plantsthat are often overlooked on more conventional Costa Rican tours. Working withan experienced naturalist and biologist, and accompanied by myself, a full-timewildlife photographer, we will be covering a range of habitats and topography.

So far Alf Jacob Nilsen has co-authored no less than 17 book titles on coral reef aquatics with Svein A. Fosså, another South Coast Norwegian. Book number 18 is to be published in 2016 (see below).

The two authors have co-operated on a lot of aquarium related projects since they first met in 1978. As authors they have learned to divide work and research efforts between them in a most effective way. With Svein having aquatics as his full-time occupation and business, and Alf Jacob having it as an all-embracing hobby and spare-time pursuit, they make a team that successfully digs into the science of reef biology and reef keeping from many angles. Below is a short presentation of the book production of Svein A. Fosså and Alf Jacob Nilsen. Links are provided for further info and ordering.
